This was not a good raptor-migration day up there, even with a NW breeze and
low clouds. I was on the Tower side. There were 2 large groups of birds
that did the same thing. First was a flock of 28 D.-C. CORMORANTS; the
next was a flock of 75 BRANT. Both appeared, coming from the north, just to
my right as I faced that direction; i.e. NNE. As they approached the
summit, the flocks slowed, broke ranks, and milled about somewhat. (Yes,
obvious even with the brant). Each flock moved about 30' toward The Lake.
Then they quickly regrouped and headed south in a direct line. What I
surmise is that, in rising to clear the Mount, they suddenly got a glimpse
of the water, and some slackers wanted to go there. The leaders, however,
after some momentary confusion, reasserted control (somehow; I heard no
sounds) and led the flock toward the prearranged destination south.
I have seen flocks of Canada geese behave similarly, but they are always
very vocal when they do so. (Discussion in committee).
I'm always impressed by individuality, even in a flock.
The above surmise is not the only option of explanation, but I think it fits
in this case.
